How short should a power cable be for my amp?

it must reach recepticle with no stress to the wire from where it stands.

There was another forum topic posted on Audiogon where people were discussing the optimal length that a power cord should be to produce the best sound. Once again I'll stick with the first comment I made on this post. BTY; I have spoken with a few major power cord manufactures and they told me power cord lengths on the short side will not impair the sound.

Long enough to plug in. It's that simple.

I have done what you are doing and in my system I found 1M to be a length that usually meets all of the requirements listed above.

How long and how thick is cool?
